The 19th-century Impressionist movement is reevaluated by contemporary art critic Matthew Collings, who asserts it was the most significant development in modern art. Collings traces its rebellious Parisian origins, starting with realist painter Gustave Courbet's allegorical critiques of government, and the groundbreaking works of Édouard Manet, and Paul Cézanne. He compares the shock value of Monet's "Impression: Sunrise" to recent art by Damien Hirst and Tracey Emin. Delving deeper, Collings explores its key principles: flatness, patterning, vibrant colors, and accurate portrayals of everyday life. He emphasizes how the Impressionists, with their lively techniques and focus on ordinary subjects, challenged the art elite's preference for formulaic and fantastical works. This documentary ultimately positions the radical French movement as a pivotal force in art history, laying the groundwork for the rise of the avant-garde.
